Today I was watching the movie Turbulence, the first one to be specific. I just had a question about how severe the storms and windshears can get. I remember hearing one of the Air Traffic Controllers in the movie talk about a level 6 storm. In the movie Turbulence II, fear of flying, Tom Berenger plays a Air Traffic Controller named Robert Sykes at Sea-Tac aka Seattle Center. When the Captain said that the Terrorist demanded that he landed immediately, the radio transmission went "negative negative Trans-Con 110 we have class 1 microburse windshears" "Redirect to clear air holding pattern over pacific" "circle 5 mile radius from VOR 228, just inland from the coast" "Fuel status"? Captain says "35,000 pounds, fuel is low, but its also low on my list of priorities right now" ATC says "Understood 110, climb and maintain 150, circle on auto, will advise FAA situation red"


Thank you all in Advance for answering. Also I wanted to thank the members of this board for advising me that it will be nearly impossible to get a job as a commercial airline Pilot without a bachelor's Degree. I have enrolled and have been accepted to Vaughn College of Aeronautics and Technology. I intend to make Aircraft operations my major with a Minor in Air Traffic Control. Classes start May 21st. I just gotta get my mind back in gear, i've been out of school since june 2001. The classes im probably going to need extra help in is Calculus(YIKES) and College Physics. I never took Physics a day in my life. But it will be worth it when im a captain one day on Delta, Continental or JetBlue!

Turbulence definitions (courtesy of the FAA's Airman's Information Manual, or AIM):

(scroll down if it's not visible, my apologies )

Turbulence Reporting Criteria Table










































Intensity



Aircraft Reaction



Reaction Inside Aircraft



Reporting Term-Definition



Light



Turbulence that momentarily causes
slight, erratic changes in altitude and/or
attitude (pitch, roll, yaw). Report as

Light Turbulence; 1


or


Turbulence that causes slight, rapid and
somewhat rhythmic bumpiness without
appreciable changes in altitude or
attitude. Report as Light Chop.



Occupants may feel a slight strain
against seat belts or shoulder straps.
Unsecured objects may be displaced
slightly. Food service may be
conducted and little or no difficulty is
encountered in walking.



Occasional-Less than 1/3 of the time.




Intermittent-1/3 to 2/3.




Continuous-More than 2/3.



Moderate




Turbulence that is similar to Light
Turbulence but of greater intensity.
Changes in altitude and/or attitude occur
but the aircraft remains in positive
control at all times. It usually causes
variations in indicated airspeed. Report
as Moderate Turbulence; 1

or

Turbulence that is similar to Light Chop
but of greater intensity. It causes rapid
bumps or jolts without appreciable
changes in aircraft altitude or attitude.
Report as Moderate Chop.1



Occupants feel definite strains against
seat belts or shoulder straps.
Unsecured objects are dislodged.
Food service and walking are difficult.




NOTE


1. Pilots should report location(s),
time (UTC), intensity, whether in or
near clouds, altitude, type of aircraft
and, when applicable, duration of
turbulence.




2. Duration may be based on time
between two locations or over a single
location. All locations should be
readily identifiable.



Severe



Turbulence that causes large, abrupt
changes in altitude and/or attitude. It
usually causes large variations in
indicated airspeed. Aircraft may be
momentarily out of control. Report as
Severe Turbulence.
1



Occupants are forced violently against
seat belts or shoulder straps.
Unsecured objects are tossed about.
Food Service and walking are
impossible.






EXAMPLES:


a. Over Omaha. 1232Z, Moderate
Turbulence, in cloud, Flight
Level 310, B707.



Extreme



Turbulence in which the aircraft is
violently tossed about and is practically
impossible to control. It may cause
structural damage. Report as Extreme
Turbulence.
1






b. From 50 miles south of
Albuquerque to 30 miles north of
Phoenix, 1210Z to 1250Z, occasional
Moderate Chop, Flight Level 330,
DC8.




1 High level turbulence (normally above 15,000 feet ASL) not associated with cumuliform cloudiness, including thunderstorms,
should be reported as CAT (clear air turbulence) preceded by the appropriate intensity, or light or moderate chop.

It's a movie. Don't expect accurate technical dialogue.

Quoting JETBLUEATASW (Thread starter):
class 1 microburse windshears

I haven't heard of such a classification of microburst, but maybe it hasn't reached my section of the industry yet.

Quoting JETBLUEATASW (Thread starter):
Calculus(YIKES)

Why does calculus seem to worry American students so much (at least from references I see in this forum)? Must be to do with how and at what age it is taught. In the UK we cover it as an integral (no pun intended) part of mathematics quite early on and people take it in their stride.

Anyway, the kind of calculus you'll need to be a pilot will be extremely straightforward, mainly concerned with the rate of change of salary with time.  Wink


The glass isn't half empty, or half full, it's twice as big as it needs to be.

I think, because, most Americans are pragmatists, and that Calculus is, by nature, a very abstract form of math...it's the art of dealing with the behavior of functions and numbers and the sort  Smile Give me a good differentiation or integration any day, but don't expect me to be able to use a LaPlace transform... (differential equations, after 3 semesters of Calculus, is why I changed my major in college from Electrical Engineering to Computer Science, which was really what I wanted to do anyways  Wink ).

Hmmm...the function for that for me tends towards zero as time marches towards infinity...the wife always tells me "keep the day job"  Wink [one of these days I'll take my commercial check ride and and the CFI ride after that, and then get paid next to nothing in my spare time to teach others to fly] Big grin
